In 1995 I first met Sherman Harrill. He had been a training companion with Tom Lewis. He then spent the rest of his life looking at the potential uses for Isshinryu technique. On that June Day he did maybe 160 application studies. The mind grown numb, when first experiencing this. At this time what sticks out was where he showed us ways to strike into the arm, and a while later I figured out how this could also be used to strike into the neck. Sherman then showed me how to use this more effectively. Later during the day he used Naifanchi stepping as a lower body drill. The whole experience blew me away.
